摘要
为获得几何偏心故障状态下两级行星轮系的传动特性,开展了仿真实验研究。以MW级风机齿轮箱中两级行星轮系为研究对象,基于SolidWorks与ADAMS建立了相应的虚拟样机,在合理设置仿真参数的基础上,进行了健康、第二级太阳轮几何偏心0.1 mm和0.2 mm这3种状态的动力学仿真。结果表明:两级行星轮系中,第二级太阳轮几何偏心故障对第一级行星轮系动态特性影响不明显,对第二级行星轮系动态特性影响较大;齿轮几何偏心故障状态下,故障频率的幅值随着几何偏心程度的增大而增大,啮合频率及其倍频的幅值随着几何偏心程度的增大而减小;边带啮合频率幅值比可以作为几何偏心故障的判别依据,可以通过该值来监测几何偏心故障的变化趋势。研究结果可以为两级行星轮系的几何偏心故障诊断提供一定的理论参考依据。
In order to obtain the transmission characteristics of the two-stage planetary gear systems under the geometric eccentric fault condition,the simulation experiment is carried out.Taking the two-stage planetary gear systems in the MW level wind turbine gear system as the research object,the corresponding virtual prototype is established based on SolidWorks and ADAMS.On the basis of reasonable setting of the simulation parameters,the dynamic simulation of the three states of healthy and second-stage solar wheel geometrical eccentricity of 0.1 mm and 0.2 mm is carried out.The results show that in the two-stage planetary gear systems,the geometrical eccentricity fault of the second-stage sun gear has no obvious influence on the dynamic characteristics of the first-stage planetary gear system,and has a great influence on the dynamic characteristics of the second-stage planetary gear system.In the geometric eccentric fault state of the gear,the amplitude of the fault frequency increases with the increase of the geometric eccentricity,and the amplitude of the meshing frequency and its multiplication decreases with the increase of the geometric eccentricity.The amplitude ratio of the sideband meshing frequency can be used as the basis for determining geometric eccentric faults,and the change trend of geometric eccentric faults can be monitored by this value.The research results can provide a theoretical reference for the geometric eccentricity fault diagnosis of two-stage planetary gear systems.
